LoRa is a spread spectrum modulation +technique derived from chirp spread specetrum (CSS) technology, and excels +at long range communication, while keeping battery usage down. LoRa was designed +exclusively for Internet of Things (IOT) applications, and is able to operate +with a large number of different LoRa end-nodes. +\subsubsection{LoRaWAN} +LoRaWAN is the communication protocol found on the MAC network layer on the network +stack. LoRaWAN, an open source protocol, interacts with LoRa to transfer data up +to the application layer. LoRaWAN leverages the unlicensed radio spectrum in the +Industrial, Scientific and Medical (ISM) band. The LoRaWAN protocol is managed +by the LoRa Alliance instead of Semtech, and serves to connect all of the end-nodes +with the gateways and the wider internet. +\subsubsection{LoRa Gateway} +A LoRa Gateway is simply the machine that runs LoRaWAN to interact with each end-node, +and usually directs traffic to another server or the wider internet. +\subsubsection{LoRa End-node} +The LoRa end-node refers to each node running the LoRa and LoRaWAN protocol. In this +project, each collar will be an end-node. \section{References} ?? \todo{Do we need this?} \section{System requirements}
